President Trump on Wednesday took fresh aim at California and its “sanctuary” laws affecting undocumented immigrants, claiming that many areas of the state want out of what he characterized as “this ridiculous, crime infested & breeding concept.”

Trump’s morning tweet was his latest salvo at the nation’s most populous state, whose laws the president and his administration contend are too friendly to undocumented immigrants.

There is a Revolution going on in California. Soooo many Sanctuary areas want OUT of this ridiculous, crime infested & breeding concept. Jerry Brown is trying to back out of the National Guard at the Border, but the people of the State are not happy. Want Security & Safety NOW!

Last month, the Justice Department asked a federal judge to block three California laws, which among other things, restrict how state businesses and law enforcement agencies can cooperate with immigration authorities.

Gov. Jerry Brown (D) subsequently said Trump was “going to war” with his state.

On Twitter on Wednesday morning, Trump also took another shot at Brown, who has agreed to send National Guard troops to the U.S.-Mexico border as Trump requested — but with restrictions that Trump finds troubling.

“Jerry Brown is trying to back out of the National Guard at the Border, but the people of the State are not happy,” Trump wrote. “Want Security & Safety NOW!”
